Means and SDs of raw total and domain-specific SRS scores at years 4, 5, and 8 as well as the number and percent of participants scoring above cut-points.

	4 years	5 years	8 years
n	186	206	227
Total	30.7 (15.3)	30.6 (20.0)	31.3 (21.9)

Mannerisms	3.3 (3.0)	3.5 (4.2)	3.9 (4.5)

Note. SRS range raw scores: Total score = 0–195, Awareness = 0–24, Cognition = 0–36, Communication = 0–66, Motivation = 0–33, Mannerisms = 0–36. Sample sizes by year: 4 years, n = 214; 5 years, n = 227.

SDs: standard deviations; SRS: Social Responsiveness Scale.
